SAN BERNARDINO — Four people were injured Sunday in a multi-vehicle traffic collision on the southbound lanes of the 215 Freeway, near the 10 Freeway interchange.

According to officials with the California Highway Patrol, a brown sedan entered the freeway on an off-ramp and drove northbound in the southbound lanes.

Four to five cars were involved in an accident with the sedan. CHP officials weren’t able to say if the driver of the sedan was intoxicated.

Two people suffered serious injuries and two moderate, said Kenny Yellen, a spokesman for the San Bernardino Fire Department.

Three were taken to Loma Linda University Medical Center and one was taken to Jerry L. Pettis Memorial VA Medical Center in Loma Linda, Yellen said. None of the injuries appeared to be life-threatening, Yellen said.

The CHP received a call reporting the accident at approximately 3:15 p.m. and fire personnel arrived about four minutes later, Yellen said.
